SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 292,164, dated January 22, 1884.

Application fllcd October 9, 1883. (No model.)

To all whom, it may concern:

Be it known that 1, JOHN GIBBoNs, of the village of West Troy, county of Albany, and State of New York, have invented a new and useful Improvement in Harness Snap-Hooks,

of which the following is a specification.

My invention relates to snap-hooks, a class of devices that are used to make harness-connections, and which are generally made with a hook having an eye or link form opening at its shank end for attachment, and a latch that is hinged to the shank and forced to engage with the point of the hook by means of a spring.

My invention consists, as will hereinafter be r 5 fully detailed in the specification and claim, of an improvement in the construction of the hinging attachment by which the latch attaches to the hook-shank. i

Accompanying this specification, and form-' ing a part of it, is a sheet of drawings containing five figures illustrating my invention and improvement, with the same designation of parts by letter-reference used in all of them, of which Figure 1, shows a plan view of a snap-hook with the latch detached therefrom, and shown as an annex, A. Fig.2 illustrates a top view of a snap-hook and connected latch; Fig. 3, a view of the under surface of the separated parts of the device turned toward the right, with the intermediate spring omitted, thelatch thus illustrated indicated as the annex figure B. Fig. 4: shows a side elevation of the de vice, with the latch forced down against the spring; and Fig. 5 is another side elevation of the device, with the latch forced to engage with the hook by the spring.

The several parts of the device are designated by letter-reference, and their function is described as follows:

The letter S indicates the shank of the hook, and H the latter; E, an opening or eye for attachment, formed in the widened-out shank end; L, the latch, and D a helical spring.

The letter O designates a sink formed in the under face of the latch to receive one end of the spring, and 0- a sink made in the upper face of the hook-shank to receive the other end of the said spring.

The letter G indicates a guide-pin on the under surface of the latch, and N a passageway for said pin through the shank, all of which parts, as thus before named, constitute the well-known construction of such devices.

As snap-hooks have heretofore been made the latches have been hinged to the shank by means of hinging-pins thatwere passed through ears on the shank, and a tonguing-piece on the latch, or by end straps on the latter that were bent around a hinging-pin on the shank, either of which methods required fitting. To improve upon these older methods is the object of my invention, and the better construction isproduced by the following means:-

The letters a a designate two rounded-out hinge-bearings made in the under surface of the shank S, and (Z (l recesses formed in the edge of the opening E and adjacent to said bearings, and p a projecting pin arranged between said recesses and parallel to the bot-tom surface of said shank.

The letters b 1) indicate j ournatpins projected from the sides of the latch at its hinging end, and adapted to enter said bearings in the shank.

The letter N indicates a recess. formed on the end of the latch between the journal-pins, and v adapted to receive the pin 19 on the shank when the parts are connected. I

To connect the latch and hook-shank thus made, the end of the hook H (indicatedat I) is cast with an-olfset-bend, (designated by the dotted line 1",) and which bend is straightened. out after the latch has been inserted. To connect the latch and shank, the hinging end of the former is passed downthrough the open ing E of the latter. The journal-pins b b on the latch are entered into the bearings a a in the shank, and the pin 1) on the latter within the recess N on the latch, by which a hinging interlocking mechanism is produced that requires no fitting for attachment, each factor of which can be made or cast with the part on which it is formed. 7

These devices, being made of malleable castings, are adapted to be bent on the hook end to receive the latch, as stated, and then bent back to retain the latter in position.

Having thus described my invention, what I constructed to connect and operate as and for claim, and desire to secure by Letters Patent, the purposes herein set forth. 1S 1' i P t In a snap-hook, the combination of the hing- JOHA GIB BO) 5 ing-pins b b and the intermediate recess, N, on I \Vitnesses:
